2 VITA CAD-Waxx for inlab Advantages and indication The material and its advantages VITA CAD-Waxx blocks can be used instead of modelling wax and consist of a filler-free acrylate polymer. They provide the following characteristics and advantages: High torsional resistance and dimensional accuracy even for large-span restorations compared to modelling wax Optimal thickness of walls and connectors for VMK frameworks; hence reduced amount of reworking is required No new model required for faulty castings; only the grinding process must be repeated Ground mouldings can be combined with casting wax or prefabricated patterns used in the casting technique Ground mouldings can be tried in situ Transparent color allows simple check of fit Can be ground with the diamond instruments of the inlab system of Sirona Burns out without residue Process optimization in the laboratory: working time is transferred into waiting time VITA CAD-Waxx for inlab / Indication table Indication Primary crown Crown framework Crown framework Cast crown Cast crown Bridge framework Bridge framework Cast bridge VITA CAD-Waxx for inlab recommended VITA CAD-Waxx is not recommended for temporary restorations and may not be cemented intraorally.

3 VITA CAD-Waxx for inlab Processing If used as a substitute for modelling wax: In conjunction with the inlab system of Sirona Dental Systems GmbH VITA CAD-Waxx serves for milling castings suitable for investing and can be used for the fabrication of primary crowns for telescopic restorations the fabrication of crown and bridge frameworks for the VMK technique cast restorations the press ceramic technique If used for try-in to check structures: Possibility of checking the fit of the structure in the mouth before fabricating the restoration using the final material. Simple processing step by step Important information: The CAD-Waxx Starter Kit from Sirona is required for processing VITA CAD-Waxx. This set (Prod. No ) can be purchased from selected dental dealers and includes a modified tank with a reinforced filter system. Ground polymer particles may cause clogging of the cooling and lubrication circulation system if the standard tank with the simple filter system is used. VITA CAD-Waxx can be milled from version V 2.7 of Sirona's inlab 3D software. When filling the tank, a reduced quantity of 5ml of DENTATEC liquid can be added for grinding VITA CAD-Waxx blocks. Place the model made from plaster suitable for scanning on the scan holder of the ineos system and carry out the scan process.* * To ensure perfect and economic processing, we recommend to carry out the scan process using the ineos system. The extremely short scanning times between 10 sec (single tooth scan) and 30 sec (bridges with 3-4 units) guarantee faster and trouble-free workflow. Additionally, the fabrication of a duplicate model is no longer required. VITA CAD-Waxx for inlab VITA Machinable Polymers page 3

Clamp in and mill VITA CAD-Waxx block CW-40. The inlab 3D software automatically calculates the minimum layer thicknesses and connector surfaces required to obtain a reliable result for the final restoration. After milling (CAM) the lug is cut off using a fine cross-cut tungsten carbide bur (red ring). VITA CAD-Waxx for inlab VITA Machinable Polymers page 4

5 VITA CAD-Waxx for inlab Processing Ground moulding on the working model. The more thickly milled edges are reduced using a cross-cut tungsten carbide bur (red ring). When processing fully anatomical mouldings, the occlusion must be checked. If desired, the ground edges of the moulding can be optimized using casting wax. Moulding on the working model after optimization with casting wax. Just like in the casting or press technique, wax sprues are attached to the moulding and waxed on the sprue former. The instructions of the alloy manufacturers or press ceramic manufacturers must be observed. VITA CAD-Waxx for inlab VITA Machinable Polymers page 5

6 VITA CAD-Waxx for inlab Processing Invest the casting in accordance with the instructions of the investment material manufacturers and place it into the preheating furnace. Important information: Do not place the casting ring into the hot preheating furnace (speed method) since VITA CAD-Waxx will expand and cracks may be formed in the investment material. Important information: Specific weight of VITA CAD-Waxx: 1.18 g/cm 3 The alloy quantity (in g) required for the restoration is calculated by multiplying the density of the alloy with the weight of the milled CAD-Waxx moulding (in g), divided by the factor Cast bridge framework made from a dental alloy ready for veneering.
